WHAT IT DOES

What local_ydb_add_storage_groups does on Local Ydb

AI agents use local_ydb_add_storage_groups to create or update resources in Local Ydb, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local Ydb environment.

RISK

Why local_ydb_add_storage_groups is rated Medium

This tool modifies database storage configuration by increasing the number of groups in a storage pool. While the change is reversible (groups can later be reduced), it affects infrastructure capacity and resource allocation. The tool provides a planning phase before execution, reducing immediate risk. It does not delete data or execute arbitrary code, placing it in the Write category.

From the tool's definition Tool description states it 'Increase NumGroups for one tenant storage pool' and 'when the update succeeds it verifies NumGroups' — this modifies storage pool configuration.

RECOMMENDED RULE

The rule that runs local_ydb_add_storage_groups safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Local Ydb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For local_ydb_add_storage_groups, this is the rule to start with:

local_ydb_add_storage_groups Rate-limited

local_ydb_add_storage_groups stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about local_ydb_add_storage_groups

What does the local_ydb_add_storage_groups tool do? +

Without confirm=true this returns the DefineStoragePool plan, rollback, target pool, and target count; when the update succeeds it verifies NumGroups and tenant metadata. It is categorised as a Write tool in the Local Ydb MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on local_ydb_add_storage_groups? +

Register the Local Ydb MCP server in PolicyLayer and add a rule for local_ydb_add_storage_groups: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Local Ydb. Nothing to install.

What risk level is local_ydb_add_storage_groups? +

local_ydb_add_storage_groups is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit local_ydb_add_storage_groups? +

Yes. Add a rate_limit block to the local_ydb_add_storage_groups rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block local_ydb_add_storage_groups completely? +
